WiFi issue

A while back, there was a big Windows 10 update and since then, I have not been able to get wifi directly from my main router. Oddly, I can connect to wifi through my D-Link extender, which has the same name, with EXT5G appended to the name. I've deleted the networks on Windows 10 and started from scratch, rebooted the router numerous times, etc. and I still can't get it to work. Any thoughts? Thanks.

You are not alone
Some people have had success by simply running the Trouble Shooter
• Right click Windows icon (bottom left)
• Control Panel (Icon View)
• Troubleshooting
• Network and Internet > Connect to the Internet
• Advanced
• Run as Administrator
• Next

another thing to look at is on the router itself -- can you do a reset (not a reboot)? using (at worst) a cable you should also be able to access its setup information.

Thanks. I did try the troubleshooter a few times. I also unplugged the router for an extended period and then plugged it in again. No luck. I did read about the drivers; but was reluctant to play around with that or the settings too much.

The Windows 10 Fall Creators Update is being released now, hopefully it will fix some of the issues created by the previous update including the wifi
The update installation seems to be getting mostly positive feedback so far but as always I recommend doing a (Macrium Reflect) image backup first
